Let me give an example, in this case to stop sambas from getting overwritten.
Idea!
You 'Tier' the Daze effects infliced on the mob by Sambas.
So: Aspir I > Drain I > Aspir II > Drain II > Haste Samba > Drain III >
Hasts Samba(Merrited)
Therefore a Mob would never get infliced by a Lower Tier Daze Effect.
So if you had a main Dancer casting a Merrited Haste Samba and a sub dancer in the Group that casts a Drain Samba I. Everyone would get the Merrited Haste Samba
instead of the person that hit last inflicting an alternate Daze effect.
that would be an Idea to prevent overwriteing. Dunno if its good but its an Idea.
